In recent years, Aluminum alloys are the most widely used material in automobile and other industries. The advantages of aluminum alloys are its less density and outstanding combination of mechanical, physical and tribological properties. In this paper a unique approach to predict tensile strength properties of aluminum alloys under room temperature to elevated condition using the fuzzy logic tool in MATLAB software is carried out. The tensile strength for various aluminum alloys available in the literatures are used as database in this research work. The developed model was validated with the previously published work. © Research India Publications.
